Creating a new file from the web interface in an external SMB storage causes all external SMB storages to be unavailable

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

The attempt to create a file with the "Add file" button in a smb external storage folder causes an error. We get an alert "Unable to create new file from template".

After this, all SMB external storage on the instance are unavalaible ("Storage with mount id ## is not available" or "External storage not available: Storage unauthorized").

The SMB external storage go back after few minutes. And we can see the file was created anyway.

Steps to reproduce

1. Mount SMB external storage for certains users
2. In Web UI, go to folder inside smb external storage
3. Click on plus button and choose "new text document"

Expected behavior

Just the possibility to create new files without crashing samba mounts.

Additional info

No response

Start with the stack trace in apps/files_external/lib/Lib/Storage/SMB.php, especially getFileInfo, and follow the template creation path through apps/files/lib/Controller/TemplateController.php and lib/private/Files/Template/TemplateManager.php. Reproduce creating a text document in an SMB folder and inspect how the timeout affects availability; done means the file is created without making the instance's SMB storages unavailable.
